Description: Squirt SEAL with BeadBlock is an ammonia-free latex solution which contains natural microfibres and BeadBlock particles. Together they form a permanent, reinforced rubber plug in punctures up to 6mm. It will prevent sidewalls sticking together. Contains corrosion inhibitors. Suitable for use from -20 °C to +40 °C. Seals punctures caused by objects up to 6mm in diameter Contains BeadBlockTM Technology Environmentally safe & Ammonia free Easy to clean SEAL’s mode of action is based on three components: latex, micro-fibers and BeadBlock™ granules. Synthetic latex liquid (ammonia-free) forms the base in which the microfibres are suspended and BeadBlock granules added. In the 150ml (5oz) size bottle, the BeadBlock granules are pre-added and only have to be added when the 1 litre and 5 litre sizes are used. On sudden pressure change (when you get a puncture), the liquid rubber quickly solidifies around the hole in the tyre. If it does not seal at once, the microfibers will start plugging the hole and in case of a puncture made by an object with a diameter of up to 6mm, the BeadBlock granules will do the rest.
